bin- Specification of Letters Patent.

To all whom it may concern: 7

Be it known that I, HARRY VISSERING, a citizen of the United States, and a resident of Chicago, in the State of Illinois, have in: vented certain new and useful Improvements in Fluid-Pressure Agitators, of which mixing devlces and more particularlyto agitators for mixing the contents of containers used for the supply of mixtures of fluids, or of mixtures including a fluid and a solid, of

, different specific gravities, and has special reference to the provisionof animproved agitator for mixing the contents of paint. barrels, such devices bein particularly useful in connection with suc paints as employ 'oil, water, or other relatively light liquid as the fluid vehicle and-lead, or otherrelatively I V both the cost thereof and that of applying tion are to provide improved means whereby the fluid contents of the barrel may be eflectively stirred up, and this with a minimum loss oftime, a minimum of expense, and without destruction of the barrel; thepro-v visionflof an improved device for the 'purpose characterized, which is provided with automatic means for restraining any acci:

dental removal? ofthe contents of the con tainer; to provide a device so characterized which maybe applied with facility to practically any known type of barrel, together with such other objectsas may hereafter ap ear.:

Much trouble curred at this dayin connection with the use of paintshaving relatively heavy, pigment and especially paints whichiare used inlarge quantities for railroad purposes, such as painting cars, bridges andthe like, since the heavy pigment settles by; gravity tothe bottom of the barrel, and in order to efficiently stir up and thereby effectively incorporate it with the oil or other j-fluidvehicle of the I paint considerable exertion on the partof,

the useris required.

,Within my observation it practically invariably occurs in such cases that the paint is not properly stirred before using and that when nearly all 'of the fluid content of the barrel isremoved, a sediment of from three to six inches'of pigment, which has'been deposited from thepaint theretofore used and which isv not available owing solely-c to the removal of its proper vehicle, will be is encountered and: loss in-:

that the pigment is wasted, second, the paint from whichit is deposited does not contain either the color or the, body which it should.

have, third, time is unnecessarily spent in endeavoring to incorporate the pigment in, the fluidvehicle by hand, to which maybe added, fourth, that in order effectively to stirupthe contents of the barrel it is neces* sary to remove one head therefrom, consequently making the barrel unfit for-"future use and thereforeunsalable, all of-which objections; not only render a given paint 7 less effective than it should be, but also make the same greater than it should be.

In theattainment of the objects above set forth and overcomingthe disadvantageous conditions suggested, I have provided the ing drawings wherein constructions illustrated in the accompany- Figuresl, 2 and 3. are sectional, perspective views'of portions of barrels having devices embodying my present invention ap- 1 plied thereto;- Fig. 4 is an enlarged detail- View of a portion of the device shown 1 in Fig.1. a I I In the drawings have indicated a barrel, 10, formed, of the usual staves, 11, and hav ing a head, 12, the staves being held in positents of the barrel and thereby efi'ectingan intimate commingling thereof, and the vcase of fluids" containing a vrelatively heavy content which should be heldin suspension mixing'it with the fluid I employ a pipe,

Thehollow plug, 18, is preferably.

threaded, int eriorly atone end as indicated at 20 for the reception of the pipe, 16,and

at the opposite end its periphery is given the ception, first, of the closing plug, 22, and,

second, for the attachment thereto of a connection, such as a pipe 23 to a source of com-I For the purpose pressed air (not shown.) of restraining effiux of the'fluid contents of the barrel through the hollow plug, 18, after the removal of the closing plug, 22, for the attachment of the pipe, 23, to such plug, 18, I employ a sliding check valve, 24:.

The form of device just described is perhaps the most economical in manufacture and the simplest in form, andisthe one preferably applied by me to barrels having a suflicient distance between the first and second hoops to permit its application.

Referring now to the device ofFigs. 2 and 3 it will be here observed that I have illustrated a form of device which Iemploy for application to barrels which have their hoops so placed that the previously described form of construction may not conveniently be employed. In the present form ofdevice it will beobserved that the perforated pipe, 15 is bent as indicatedHa-t 25 and in lieu of the sliding check valve of the first mentioned device I employ the ball valve, 2%. The bend at 25 permits in sertion of the pipe through and fastening of the plug. in the bottom of the barrel, Without disturbance ofits parallelism to such bottom. 7

In mixing paints containing an extra heavy pigment and other fluids, for the mixing ,of which the devices of Figs. 1 and 2 would be inadequate, I preferably. employ the form of device shown in Fig. 3 in which it willbe observed oninspectio'n ofjFig. 3

that the pipe 15 is given the form of a continuous spiral, I being thus enabledto, as t were, SQIGW lt 1I1t0 tl1e barrel through a brittom openlng.- In order to secure the mosteifective results from the. use of com-y pressed air, the perforated pipe .15, should be kept substantially parallel to, the bottom of the barrel and shouldnot, be placed too far away from' the sediment, and it apparent t'hat the useofthespn'al form of p pe peri'n ts the placing of .an increased length thereof in the, barrel without remow in'g any naterial portion thereof from the normal level of the sediment.

I. have found thatinthe use of barrels equipped with my improved. agitator, when a hole such indicated at 26' is bored threugh. the heajd .l 3, (if the barrel, it is unnecessary to remove the upper head of the barrel since such hole is adequate t6 relieve the air pressure by venting it to the atmosphere. IVhen the barrel is standing in the position indicated in the drawings,

the agitator arranged across the bottom, and

air admitted to the perforated pipe under pressure, not only is the whole fluid content of the barrel, such as the vehicle and 'pigment held in suspension therein, thoroughly stirred up and mixed without the least efl'ortonthe part of the workmen, but also any sediment which may have been precipitated to the bottom of the barrel is washedup therefrom by the air blast and thoroughly.commingled with such fluid content. 7

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:

1. In an apparatus of the character described, in combination, a hollow plug provided with means whereby it may be attached to a container, means for connecting the hollow plug to' asource of fluid pressure and a stop-plug for preventing gravitation outwardly of fluid through said hollow plug, a check valve adapted to act as an auxiliary means for such prevention on the removal of the stop-plug.

2. In combination with a container, an agitator comprising, in combination, a hollow plug eXteriorly threaded to engage with said container, a perforated pipe carried at one end by said plug, saidpipe being closed at its opposite ,end and arranged substantially horizontal to and having its major portion spaced away from the head of said container, and a connection through said plug for a source of compressed fluid, eX- ternal means for closing said connection, and a check valve for restraining back flow of fluid through said connection.

3. In combination with a container, an agitator comprising, in combination, a hollowplug eXteriorly threaded to engage with said container, a closure for said plug disposed eXteriorly of the container, and a perforated pipe having threaded engagement with said plug at oneend thereof, the opposit'e end of said plug being threaded for the reception of the closure and adapted for a connection to a source of fluid pressure,
